Braid lines tested
February 18, 2008, 09:04:15 AM
Here is a link to a Sportfishing mags recent(?) tests on lines, knots etc.
Different kettle of fish I understand, and light lines also, but worth a read all the same!

Bimini's aside, I will relook at the other knots I'm tying for my lighter fishing.

Cheers Dave  :)

Interesting read, what's your thoughts on the 12-turn Bimini??

Absolutely positively bloody hopeless   :D

On the plus side though it takes 1/6 the time to twist up  :D

I recall Neil from Jones Tackle did a very comprehensive test on braid knots / Bimini's under working conditions.
The thread is somewhere on the site. 
I dont think Bimini's with minimal twists rated at all well by his methods of testing.

I will dig it up and have a re read as it covered everything.

Cheers Dave

Neil'test's:

I hope some of this post answers a few questions out there.

These results were achieved using an digital force gauge measuring in 10gram increments, however all figures have been rounded to the nearest half kilo to simplify things.
The line used was new unused 80lb XP Tuff Line, because it's well known and I use and recomend it.
Reel and Rod used in tests were Stella 10000 and Tokara 60.

Line tested no knots - 44 kg. This is a very good figure as it's well over the stated b/s. To get pounds b/s multiply by 2.2 is close enough.

Test 1. (gradual force is used to get highest b/s. 3 tests each knot)
Bimini Twist 70 turns - 41 to 43.5 kg
Bimini twist 30 turns - 21.5 to 30 kg
Midknot - 23 to 28 kg
Test 2. (moderate shock is applied - something like small fish) No elasticity or bungy is involved here that comes later.
Bimini Twist 70 turns - 31 to 35 kg
Bimini Twist 30 turns - 15 to 18.5 kg
Midknot - 21 to 25 kg

Test 3. (heavy shock applied - like big fish) Still no bungy.
Bimini Twist 70 turns - 14 to 16 kg
Bimini Twist 30 turns - don't bother
Midknot - 9.5 to 11 kg

Test 4. ( sharpest shock possible applied) No bungy. This ones scary only did it once.
Bimini 70 -- 8.5 kg
Midknot -- 8.5 kg

Test 5. Super twisty leader is added to 70 turn bimini and test 2 3 4 repeated.
Super twisty is 3.7m long provides 60cm of bungy at 30kg of force.
2. - 40kg
3. - 25 kg
4. - 16 kg

Midknot not tested, however the small amount of stretch in single strand mono leader will provide a small benefit as the stretch is way less than 60cm.

Sturgeon leader is slightly stretchier than twisty - 80cm per 3.7m at 30kg
This will provide good results, however, I don't trust braid to braid connections and that seems to be the only way to re-rig in a hurry.( That is, like a standard wind-on with a much longer braid loop section)

This could develop into a full blown Thesis, I have another set of figures doing the tests through rods and reels.

Reel only with 15kg drag setting, no bungy
Heavy shock applied - 23 to 27 kg
Heavy shock with bungy - 21 to 24 kg

Reel on rod with 15kg drag setting and bungy leader ( rod held at 60 degrees)
Heavy shock applied - 19 to 21.5 kg


A brief summary goes like this,
Bimini is king.
Bungy is good.
Don't use Midknot on 80 braid with 15 kg drag setting and mega gt it may just go bang.
Theoretically a good bimini in 80 braid with twisty leader and 15 drag setting is unbreakable.
